Manual for maintenance of multi-host ixodid ticks in the laboratory

Abstract

Use of laboratory animals as hosts for blood-sucking arthropods remains a time-proven and the most efficient method for establishment and propagation of slowly feeding ixodid ticks, despite introduction of techniques involving artificial feeding on either animal skins or synthetic membranes. New Zealand White rabbits are usually the most accessible and most suitable hosts routinely used for establishment and maintenance of a large variety of multi-host tick species. Here we describe standard procedures for maintaining colonies of multi-host ixodid ticks by feeding all developmental stages (larvae, nymphs, and adults) upon New Zealand White rabbits. When needed, the same procedures can be easily adapted to other species of laboratory or domestic animals from mice to dogs and goats. A summary of our experience in maintaining laboratory colonies of Ixodes scapularis, Ixodes pacificus, Amblyomma americanum, Dermacentor variabilis, Dermacentor occidentalis, Haemaphysalis leporispalustris, and Rhipicephalus sanguineus with descriptions of the complete laboratory life cycles and reliable production of uninfected ticks under standardized conditions has been published by Troughton and Levin (J Med Entomol 44:732–740, 2007). Here we provide step-by-step recommendations for various procedures used in the maintenance of ixodid tick colonies based on over 20 years of experience.
